Try this science experiment with children over the course of several days. Fill up 4 vases with different coloured water and put 1 white carnation in each one. Watch the flowers over the next four days change to the colour of the water.
Loved this programme as a child, the programme was part of a BBC children's television series titled Watch with Mother, with a different programme each weekday, most of them involving string puppets. The Flower Pot Men was the story of two little men made of flower pots who lived at the bottom of an English suburban garden. The characters were devised by Freda Lingstrom and Maria Bird.
